[alsa-devel] [PATCH 15/20] ASoC: S3C: I2Sv2: Unify i2s_get_clock callback

[Jassi Brar]

Now that we have two callbacks s3c2412_i2s_get_clock & s3c64xx_i2s_get_clock
doing exactly the same thing, we can define one generic s3c_i2sv2_get_clock
and discard other two copies. Also, switch the users to make calls to the
newly defined and generic s3c_i2sv2_get_clock
